I dont give a rats ass about how long theyve stayed, i know the scheme and the product on the field on D has been he exact same with multiple DCs. I dont care if he is hard to work for or a saint, if were going to be what we say we are he needs to let manny do his thing. Dans way has been pure garbage for the last 4 good teams we have played.
It is pretty clear that Mullen has a defensive philosophy that he is partial to, and he hires his defensive coordinators accordingly....but I'd be willing to bet that he is not dictating the defensive calls in the game.
